How does stretching exercise of the ankle joint affect balance and gait function in healthy older adults aged 65 to 75 years?: A randomized clinical trial.
Trial report in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study aimed to examine the effects of ankle joint stretching exercises on gait function in older adults and to clarify their relationship with balance control. Specifically, the study compared the outcomes of simultaneous stretching of the plantar flexors and ankle inverters with those of stretching the plantar flexors alone.
methodsIn this single-blind randomized controlled trial, 40 healthy older adults aged 65 to 75 years (36 women and 4 men; overall mean age, 69.0 ± 2.9 years) were randomized (1:1) to either the experimental group (simultaneous stretching of the plantar flexors and invertors) or the control group (stretching of the plantar flexors only). Each group performed stretching exercises for 30 minutes/day, 5 days/week, for a total of 15 sessions over 3 weeks. The primary outcome was the Ankle dorsiflexion and eversion range of motion (ROM), Berg Balance Scale (BBS) score, Timed Up and Go test (TUG), gait parameter, center of pressure (COP) parameter.
resultsBoth groups showed significant improvements in ankle dorsiflexion ROM, BBS, step cadence, and double support time in gait after the intervention. However, only the experimental group showed significant improvements in ankle eversion ROM, mediolateral COP range, step velocity on both sides, and TUG performance. Between-group comparisons revealed that changes in eversion ROM, mediolateral COP range, and TUG performance were significantly greater in the experimental group than in the control group. No significant between-group differences were observed in dorsiflexion ROM, BBS scores, step length, step duration, mean COP velocity, or cadence.
conclusionAnkle stretching exercises improved balance and gait function in healthy older adults, with greater effects observed from combined stretching of the plantar flexors and invertors. These benefits are likely due to enhanced postural control and increased ankle flexibility.
